Dave has posted some screenshots of Roller 2.0. I have to say, the new UI is a big improvement, both with colors and fonts. I hope to try 2.0 out today and hopefully get it installed at Virtuas in the next week or two. I can't wait until this release is installed on JRoller - it'll be very cool when many people can participate in a SourceBeat blog. Nice work Dave!
FWIW, I plan on hanging out in #appfuse and #roller on irc.freenode.net this week. Stop by and say hi if you have questions about either project.
